This article reflects on the changing environment through the passage of time and how certain technologies for a creative proposal allow the preservation and transmission of a significant part of that ephemeral heritage for future generations. The general purpose of this particular project is aimed to achieve the sound synthesis of a specific and representative cityscape as the old train station in Cuenca –located in the heart of the city– that could be preserved and reproduced as an unique document of a present time, ascertainable in the future: a memory that interpret sound as a time capsule. This soundscape was made to mark the arrival of the high speed train in 2010 to a brand new station in the outskirts of the city. Therefore, the goal of this research was focused on achieving a synthetic document that provided a sound memory capable of reflecting the significant social, cultural and logistical features, of what was until then the only railway communication symbol in the city of Cuenca from 1883 to the first decade of the 21st century.

Pío Collivadino was a highly recognized painter in life, occupying the most important charges in the artistic field and receiving awards in his country and abroad, which turned him into an inescapable reference of young Argentinean artists who earned recognition throughout the twentieth century. Why, then, with the time, his work began to fall to the wayside? In response to this question, the present article, based on the analysis of the work of that artist, proposes to problematize the notion of subjectivity, both in its individual dimension and its national character, underlining the role that the figure of the artist meets for its formation. Developing the concepts of light-color and body-mass, from Collivadino painting, this article will attempt to explain the relation between the emergence of an Argentinean subjectivity, at the beginning of 20th century, and the art, not only at the level of the issues addressed, but, especially, taking into consideration its formal characteristics.

Conceptual art and communicator role has influenced the work of Chilean architect Alfredo Jaar, which has been proposed report, with other codes [verbal and nonverbal], global events influencing contemporary society. His early training as an architect has driven innovation in the design of artistic space , using the message to convey to the viewer the reason for his work for more than three decades, highlights the artistic composition with various material resources whose purpose lies in conceptualizing various topics relevant in considering the role of artistic communication. Jaar’s style is the sum of his own life experience in relation to the contradictions of the world today, which is exposed and from the perspective of postmodernism from the exploitation of the notion of space as an open stage for visual and expressiveness beyond national borders, societies and cultures of the world.

Currently new digital tools used in architecture are often at the service of a conception of architecture as a consumer society’s cultural good. Within this neoliberal cultural frame, architects’ social function is no longer seen as the production of urban facts with sense of duty, but as a part within the symbolic logic that rules the social production of cultural values as it was defined by Veblen and developed by Baudrillard. As a result, the potential given by the new digital tools used in representation has shifted from an instrument used to verify a built project to two different main models: At the one hand the development of pure virtual architectures that are exclusively configured within their symbolic value as artistic “images” easily reproducible. On the other hand the development of all those projects which -even maintaining their attention to architecture as a built fact- base their symbolic value on the author’s image and on virtual aesthetics and logics that prevail over architecture’s materiality. Architects’ sense of duty has definitely reached a turning point.

The goal of this study is to identify cues for the cognitive process of attention in ancient Greek art, aiming to find confirmation of its possible use by ancient Greek audiences and artists. Evidence of cues that trigger attention’s psychological dispositions was searched through content analysis of image reproductions of ancient Greek sculpture and fine vase painting from the archaic to the Hellenistic period - ca. 7th -1st cent. BC. Through this analysis, it was possible to observe the presence of cues that trigger orientation to the work of art (i.e. amplification, contrast, emotional salience, simplification, symmetry), of a cue that triggers a disseminate attention to the parts of the work (i.e. distribution of elements) and of cues that activate selective attention to specific elements in the work of art (i.e. contrast of elements, salient color, central positioning of elements, composition regarding the flow of elements and significant objects). Results support the universality of those dispositions, probably connected with basic competencies that are hard-wired in the nervous system and in the cognitive processes.

In 1990, Juan Antonio Ramírez made known his iconological paranoiac method to the academic world. It is a system devised to study Dalí´s work, born of happy matrimony between the catalonian artist´s critical paranoiac method and the first iconographic school of Warburg and Panofsky. What, at first sight, seemed to be an extravagant methodology with little academic credibility, turned out to be, by going forward in time, an effective research method when analyzing Dali´s initial works. It is no wonder that, at the beginning of XXI century, this hybridization between Dalí´s and Panofsky’s methods, were regarded as a strange and nonsensical idea. Nevertheless, twenty years after, blatant examples have been noted, which endorse the advantages of this new system for “iconographic” study. As usual, this new contribution by Juan Antonio Ramirez to art history methodology is called upon to have a successful future survival, in forthcoming generations. This article, attempts to analyze this method, inquiring into the validity, effectiveness and practical utility.

This article is the result of a research that analyzes the most important artistic proposals of Visual Arts in Ecuador, since the second half of the twentieth century to the present. Through literature review and data collection held in the city of Guayaquil, we could determine their influence and impact on the circuit of contemporary art. The instruments used for data collection were depth interviews that were done to experts in the field. Like surveys of attendees at different artistic events (exhibitions, permanent exhibitions, seminars), allowed to establish the social interests of those proposals. The methodology was mixed approach, quantitative and qualitative data were used.

Para la mentalidad colonialista del siglo XIX la raza negra estaba provista de una extraordinaria sexualidad y lujuria. En la metrópolis el equivalente era la mujer sexuada, la prostituta. En los primeros años del siglo XX este tándem, prostituta-colonizado, sirve a los artistas vanguardistas como elemento de confrontación con la moral imperante. Son las artistas mujeres, con una intención feminista, quienes principalmente utilizan el primitivismo asociado a la mujer en su crítica a los estereotipos. Figura pionera en ello es Hannah Höch, especialmente en su serie De un Museo Etnográfico, en el que asocia figuras femeninas y objetos de arte primitivo. En los años 70 del siglo XX, algunas artistas de la performance, como Carolee Schneemann o Ana Mendieta reivindican el cuerpo femenino con el significado de Origen y Fertilidad que tiene en las culturas primitivas. En este mismo contexto puede inscribirse la escultura Maman de Louise Bourgeois. El elemento de crítica social, que está vigente aún en nuestros días, puede verse en las obras de las Guerrilla Girls.

Se trata de hacer una lectura estratégica de pensadores contemporáneos (filósofos, teóricos literarios y retóricos) para mostrar cómo contribuyen a configurar una retórica contemporánea dedicada al estudio crítico de cuestiones actuales del discurso en su constitución y en sus efectos en las Humanidades. Cuestiones como la eficacia y la oportunidad del discurso, su apropiación y su potencial crítico. En la medida en que el discurso es aquello por lo que se lucha y no el instrumento para luchas exteriores a él, la importancia de los vocabularios y de las figuras para resistirse y criticar las formas de dominación resulta indudable. Las representaciones no son simples imágenes verídicas o engañosas de una realidad que le sería externa, poseen una energía propia que persuade y convence de que el mundo es en efecto lo que dicen que es y que constituye a los sujetos del discurso así como sus relaciones sociales. A esa energía la retórica le ha llamado desde siempre retoricidad o fuerza retórica de la lengua. Parte de esa fuerza retórica de la lengua radica en la capacidad que posee cierto vocabulario para producir conmociones políticas en las sociedades y modificaciones en las formas de subjetivación de los individuos. El título Estrategias retóricas se refiere a dichos vocabularios críticos. El curso tiene duración de un año.

A Primeira Exposição Colonial Portuguesa realizada no Porto em 1934 foi a consequência visível do impulso que Salazar quis dar à «política colonial» portuguesa e a uma orientação imperial em que colonizar e civilizar as populações indígenas eram as palavras de ordem. Como corolário da exposição foram produzidos, entre outros, dois importantes álbuns, hoje documentos de inegável interesse histórico, não só enquanto discurso de propaganda do regime do Estado Novo, mas também enquanto narrativas visuais ou “visões do Império”. São eles, o Álbum Fotográfico da autoria do fotógrafo Domingos Alvão e o Álbum Comemorativo, com reproduções de pinturas e desenhos do pintor Eduardo Malta. Neste trabalho pretendemos reflectir sobre essas “visões do Império”, pois elas expressam uma visualidade e um imaginário que se traduz em práticas sociais, em valores e em relações de dominação que definem uma política do olhar, onde o corpo se torna um espaço de inscrição, bem como de categorização racial e cultural. Em suma, é através dessas imagens que vemos as relações de poder e as formas de dominação sobre o outro, que impregnaram a exposição.

Durante El Niño 1997, se estudiaron los sedimentos marinos superficiales de la bahía del Callao (11°50’S a 12°06’S), en 68 estaciones de muestreo situadas al interior de la bahía, incluyendo Ventanilla. Se situaron 35 estaciones complementarias entre las desembocaduras de los ríos Rímac y Chillón donde se concentran las descargas de desechos industriales, urbanos y de actividad portuaria. Se realizaron tres transectos, frente a: playa Ventanilla, al colector Comas y a Chucuito-La Punta. Frente a la playa Márquez se encuentra textura areno arcillosa y hacia el norte predomina el fango; frente a Oquendo las texturas son fango y arena arcillosa. Sedimentos de grano fino, con textura limo arcillosa y arcillo limosa existen en el fondo marino de zonas más profundas y alejadas de la costa; pero también están cerca de la costa, al sur y suroeste de la zona de operaciones portuarias, frente a Chucuito y La Punta. Texturas de arena se registraron al norte del río Chillón (La Pampilla y Ventanilla), en los alrededores del banco Camotal y frente a La Punta. En las áreas más profundas y abrigadas de la bahía, los sedimentos con granulometría muy fina presentan valores negativos de asimetría, característicos de ambientes de sedimentación. En sectores donde existen sedimentos de grano más grueso ocurren procesos de transporte (tipo y forma de ondulaciones) y erosión, apreciables en imágenes del fondo, y en el análisis de parámetros estadísticos. Los altos contenidos de materia orgánica se encuentran asociados a sedimentos de grano fino en ambientes de sedimentación principalmente, está condicionado por la tasa de aporte y origen (antrópico, marino o continental) y por las condiciones de escaso oxígeno que favorecen su preservación. Los más bajos contenidos orgánicos frente a la zona costera de Ventanilla, están asociadas a sedimentos con predominancia de fracciones de arena y origen terrígeno y mayor oxigenación.
